Fluorescein Isothiocyanate-Dextran - Sigma-Aldrich

WebDextran is essentially a linear glucose chain linked by α-D-(1 – 6) linkages. The degree of branching is about 5 %. The fluorescein moiety is attached by a stable thiocarbamoyl linkage and the labelling procedure does not lead to any depolymerization of the dextran.

How can I determine approximate size (nm) of dextran

WebA bi-directional Caco-2 permeability assay is performed where the transport of the compound is measured in the apical to basolateral direction as well as the basolateral to apical direction. The result is typically reported as an efflux ratio i.e. P app (B-A)/P app (A-B). If the efflux ratio is greater than two then this indicates drug efflux ... WebTo evaluate the capacity of drug permeability through nasal mucosa, TEER and permeation coefficients ( Papp) are determined. Measurement of TEER involves determining resistance to ion flux between the apical and basolateral sides of the cell monolayer; therefore, this method allows the integrity of TJs between cells to be evaluated.
